SPECIFICATION forming part of Letters Patent No. 597,893, dated January 25, 1898.

Application filed July 21, 1897, Serial No. 645,453. (No model.)

To til whom it may concern;

Be it known that I, Lure-a FILIPPO CAMPI, an Italian subject, residing at New York city, in the county and State of New York, have invented a new and useful Milling-Machine,

of which the following is a specification.

My invention relates to an improved machine for cutting trimming-dies, the object being to do this work in a more rapid, eco nominal, and perfect manner than heretofore. This object is attained in part by the use of a pattern which serves as a guide and prevents the cutting-tool from going wrong and enables an unskilled workman to operate the machine.

My improved machine is illustrated in the accompanyingdrawings, in which- Figure l is a front elevation, Fig. 2 a plan, and Fig. 3 a transverse section on the line X X of Fig.

- Similarletters refer to similar parts throughout the several views.

The machine proper is supported upon a table A, having legs B B. To this is securely fastened. an upright standard C,pr0vided with a groove G, into which is fitted by a dovetail joint an arm' or bracket D, which is free to move in the groove 0 from the front to the back of the machine. This arm D on its rear face has a longitudinal groove D, within which is fitted by'a dovetail joint a block E, which moves freely within the groove D 1011- gitudinally of the machine. A lever F, having a handle G, is secured to the table A by a universal joint H, audfby a similar universal joint I the said lever is secured near its upper extremity to a bar J, which bar is rigidly connected with the block E through an elongated slot D in the arm D.

Supported upon standards K, near the four corners of the supporting-base, is a series of frames, the lowermost of which, L, is rigidly secured to the standards K. The interior edges of the frame L, running longitudinally of the machine, are grooved to receive projecting portions upon the under side of the frame M, which permit the frame M to reciprocate in a longitudinal direction in the grooves of the frame L. Uponthe upper side of the frame M are grooves running in a transverse direction, and in these is fitted a frame N, which is thus adapted to move transsuitable source of power.

versely. To the frame L there is secured a screw-threaded rod m, the screw-threads being adapted to engage with a nut rigidly secured to the frame M. By means of this rod the table M is moved longitudinally when desired. A similar rod n and nut it serve in like manner to move the work-supporting table N in a transverse direction. The openings in the frames L, M, and N normally coincide and are immediately over the support or block E. The bar J is rigidly secured to the block E near the middle thereof. Upon the right side of the block there is rigidly supported a tracing-point O, which projects through the openings in the several tables and to a point substantially on a level with the top of the table N. On the left side of the block E there is secured a milling-tool P. This tool P is secured with a chuck Q by any usual means. The chuck Q has its bearing in the block E, and this hearing is tapered slightly to take up wear. Upon the lower end of the chuck is mounted a pulley R, to which motion is communicated by a belt S from any Since in the operation of the machine, as will be later explained, the distance between this pulley R and the source of power is continually changed, I have provided an appliance for taking up the slack of the belt. This appliance is seen in elevation in Fig. 1 and in plan in Fig. 2 and consists of two idler-pulleys T and T, under which the belt is carried, and which pulleys are mounted in the movable frame U, which is pivoted to a support V, and from the upper end of the frame near the idlers T and T is suspended a weight -W, which when the belt is slackened tends to draw down the idler-pulleys and thus tighten the belt sufiicientlyto convey power. In order to prevent the belt being thrown off the pulley Bwhen these idlers T T are drawn down,

I provide another pair of idlers Y Y, be-

tween the pulley R and the idlers T T, over which the belt runs and which maintains a straight draft of the belt upon the pulley R.

Having now described the construction of my machine, I would point out its mode of operation. A pattern Z is securely fastened to the frame N upon the right-hand side of the same and immediately over the tracing-point O, and upon the left-hand side of the frame i ii N liei fastenedthepieee er imetaiZ ate opi RGIVEJT iElieeperatorgrasps thehandle G and: incans 'oi'same eansesthetraeingepointO "the?pattern deeigns The znilling mg mevedwhytthe samehandle ever 7 V ,anrexaetly simitar; pat! iii entti-ng re liefia'm'eda sign the-pattern f'the deeign' "s;
